MODELING OF FREE AND FORCED LONGITUDINAL OSCILLATIONS OF A STRAIGHT ROD USING THE DIRECT DISCRETIZATION METHOD

In the study of the dynamics of mechanical systems with distributed parameters, the discretization of partial differential equations by the finite element method, finite difference method, or boundary element method is widely used. This makes it possible to simplify the analysis of dynamic processes by reducing it to solving a system of ordinary differential equations.

Feature screening algorithm for high dimensional data

Currently, feature screening is becoming an important topic in the fields of machine learning and high-dimensional data analysis.  Filtering out irrelevant features from a set of variables is considered to be an important preliminary step that should be performed before any data analysis.  Many approaches have been proposed to the same topic after the work of Fan and Lv (J.
